A car is traveling south at a speed of 68 mi/h from Dallas toward San Antonio. Dallas is about 272 miles north of San Antonio. A truck is traveling north from San Antonio to Dallas at a speed of 71 mi/h. When and where will they pass each other?
1. Create a table to record the highway distance from San Antonio for 05 hours in onehour intervals.
2. Graph the information in your table. Put time on the xaxis.3. What do the yintercepts on your graph mean?
4. Where do the cars pass each other?
5. Which vehicle reaches its’ destination first?

I will assume you meant to state that they left at the same time.
Let the distance covered by the southbound be x
let the distance covered by the northbound be 272x
time for southbound = x/68
time for northbound = (272x)/71
solve: x/68 = (272x)/71
71x = 18496  68x
139x = 18496
x = 133.06
the southbound car went 133.06 , and the northbound went 138.94 miles when they met
time = 133.06/68 = 1.957 hrs
( check: 138.94/71 = 1.957 hrs )
Just follow the instructions for the remaining part of the question.
